The given invention avails itself of the type of energy which has been wasted until now .The device consists of a floating structure with a hole in it connecting the ocean through its lower side and the atmosphere through its upper side. The hole, filled with water (a.k.a. “moonpool”) can be excited in a vertical motion by the incoming waves. The floating structure, in turn, is also excited by the waves. A relative motion between them is thus generated, while electricity production is maximised. Wave energy conversion is carried through a specific type of water turbine, eg. Well’s or any other powertakeoff.

 

VANTAGGI

  • reduced dimensions comparing to similar devices;
  • low market saturation as it regards wave energy conversion in small seas
  • contribution to the fossils-free-future paradigm: affordable renewable energy;
  • higher efficiency due to the capacity to generate greater amount of energy from waves

  • especially suitable for electricity supply in small islands, often suffering from resource scarcity;
  • particularly efficient to converse wave motion within wave climates with moderate energy content.

The inventor will present the technology at RemTech Expo (Ferrara, 19-21 September 2018)
